There are dedicated Film Recorders.

A popular device is a Kodak LVT Rihno, LVT stands for (IIRC) Light Valve Technology.
You have to find a lab providing that kind of film print service, you will obtain perfect negatives, look for rhinos...
Genesis exhibition by Sebastiao Salgado used negatives printed with a Rihno. His post 2007 work was made with canon DSLRs, so they had consistency problems to match TXP 120mm negatives shot with Pentax 645. Amazonas production staff (editing Genesis work) ended editing the digital images (also introducing synthetic grain) to match the TXP, then printed it on 8x10" Delta 100 with the Rihno, 4 images per sheet, and finally they made optical enlargements.
I guess that they wanted to sell part of the globally exhibited material (there were multiple series in every country), and collectors usually buy optical stuff.
This was a remarkable job... I guess that when Taschen is near...
